What is a 12 volt heater?

A 12-volt heater is an excellent camping accessory that can help make your campervan or RV trip more comfortable. These heaters are powered by DC current from a battery and can provide your vehicle with the warmth you need in cold weather. 12-volt heaters for campers can often be used in combination with other heating sources such as propane and other heating fuels.

These heaters use less power than other types of heaters, which makes them ideal for people who are camping in their cars or RVs.

Why would you need a 12 Volt Heater For Your Camper?

12 volt heaters are ideal for use in motorhomes, caravans, vans, trucks and other types of recreational vehicles. They can also be used for boats and many other applications where there is no mains power available. Such heaters are ideal for providing additional heating if you do not have access to a mains electric supply at all times during your trip.

One of the most common reasons people use 12 volt heaters is because they love camping in places that don't have electricity. In many cases, campgrounds will limit electrical use by installing meters or using generators and charging campsites by their consumption of electricity.

Types of heaters for campers

There are two main types of 12 volt heaters for campers. They are the fan-forced type and the ceramic type. The fan forced type is similar to a regular heater in that it has a heating coil, but this heater also has a fan to help circulate the warm air around the interior of your tent.

The second type of 12 volt heaters are made from ceramic materials and they use electricity to heat up their internal ceramic plates. This type of heater works by directing warm air into your tent through a series of vents.

Both of these types of 12 volt heaters are silent and will produce no fumes. If you leave them on all night, your tent won't stink up like it would if you were using an open flame or propane heater.

How much power does it use?

A 12 volt heater will usually use around 8 to 14 amps per hour. Most models have a thermostat built into them so that they only turn on when it's cold enough outside for them to work properly. This means your battery won't get drained by running these heaters all night long.

Advantages of a 12 volt heater

In the past, RVers had to bundle up in warm clothes and blankets instead of enjoying the true freedom of camping. It was tough to stay warm when temperatures dropped outside, especially during the night.

  • Keeps you warm
  • The most obvious benefit of 12-volt heaters for campers is that they keep you warm when it's cold outside. Even if you are used to camping in colder weather and are prepared to cope with it, being warm is always welcome on a camping trip. With a 12-volt heater, there's no reason to suffer through being cold all day long.

  • Easy Installation
  • Camping is supposed to be fun, not stressful. So why deal with the hassle of trying to install multiple propane bottles and hook them up to a propane heater? With a 12-volt heater, all that you have to do is plug it into your cigarette lighter or power outlet and turn it on; there's no need for any extra equipment or installation!

  • Ideal for small RVs
  • Many campers like to stay in smaller, less expensive RVs during the summer season. Unfortunately, these smaller models often don't come with reliable heating systems, which makes them difficult to enjoy during the colder months of the year. Fortunately, 12 volt heaters are easy to install in virtually any RV and require very little room. Simply purchase one from an automotive parts store or home improvement store and have it installed before your next winter camping trip.

  • Can be used in any season
  • The 12-volt heaters for campers are designed so that they can be used in any season as well as every climate condition. They are made from high quality materials and are able to withstand extreme cold temperatures as well as extreme heat temperatures. This makes them ideal for a family of four or more who love outdoor activities.

  • More peace of mind
  • Modern 12 volt heaters are very compact and easy to install, which makes them a perfect addition if you're looking for a way to stay warm while camping. Setting up a smaller heater means less space taken up in your RV, which can make all the difference when it comes to comfort.

    A smaller heater can also mean more peace of mind for your family and friends. A small heater will take up less space than larger ones and won't cause any safety concerns for those who are staying with you during the winter months.

  • Economical and efficient
  • When looking at the cost of these heaters, you must take into account how efficient they are. The savings on energy costs alone will pay for the unit in just one winter season! Even though some models are more expensive than others, they all have a very low operating cost which makes them every penny!

  • Compact size
  • Because of their size, these heaters can be placed anywhere in your RV without taking up too much space. This can also mean that they're more energy efficient, as they don't need to use as much energy to warm up the air around them. This means that you'll save money on electricity costs.

  • Extremely safe
  • There are so many different types of heaters on the market today. It can be a daunting task finding the right heater for your camper. The best way to go about it is to know what features you need and start searching for them. A 12 volt Camper heater is a great choice for many people because they are lightweight, portable, and easy to install. It works by converting the car’s battery into heat energy, which is then circulated throughout the vehicle.

    The best thing about using a 12 Volt Camper Heater is that you don’t have to worry about fuel consumption or emissions from your car. Many people are concerned about their emissions these days and want to reduce their carbon footprint as much as possible. With a standard water heater, you may have to burn oil or coal in order to generate enough heat energy to warm up your home or cabin. With a 12 Volt Car Heater, you don’t have to worry about this at all because it doesn’t use any fuel at all! It also means that you don’t have to use electricity in order to generate hot water either.

  • Lightweight design
  • Many of these heaters are small and lightweight so that you can easily carry them around with you when you go on a hike or other excursion away from your camper.

  • Long-lasting
  • Most of the time, when you purchase an item for your RV, you want to be sure that it will last for a long time. This is especially true for any items that are electrical or fuel powered. The 12 volt heater is definitely something that will last because it doesn't use much energy and it has no moving parts that can break with normal use. Even if your heater was to break, it would be covered under warranty by the manufacturer.

Disadvantages Of A 12 Volt Heater

The first disadvantage is that it's not as powerful as a regular heater. It's only going to produce a small amount of heat and it may not be enough to keep you warm. When you're looking at a 12-volt heater for campers, make sure that it has enough power to keep you warm. Some of them only have two watts of power, which isn't nearly enough to keep you warm.

Another disadvantage of 12 volt heaters is that they're more expensive than other types of heaters. This means that if you're trying to save money on heating costs, then this isn't the best choice for you. The downside is that if you don't use it correctly, then it could cost you a lot more money than it should.

It's also important to know how long it will take for the heater to start working properly. Many people think that these heaters are like regular ones and only take about twenty minutes to warm up.

Problem with camping in winter

One of the major problems people have with camping in winter is keeping themselves and their gear warm. Even if you're doing it in an RV that has a full-size heater, it can still be challenging to keep yourself comfortable.


These heaters run on 12 volt power and are designed to be as simple as possible. The beauty of these heaters is that they can be used in any season. In summer, you can use them to ventilate your camper; in winter, you can turn them into an instant heater.

One solution is to use 12 volt heaters for campers. These are small and portable, so you can place them where they are needed, and they can be used in any season. This makes them an excellent investment for anyone who camps regularly throughout the year.

The 12 Volt Heater for Campers makes it easy to stay warm on those chilly nights while you're camping. This heater has an extremely lightweight design, making it easy to pack along with your other camping gear. You can hook it up to your car or truck battery, or use an AC adapter at home if you want to use it during the winter months as well.
